Answer

Correct answer:B

Step-by-step solution

Standard Method

Given: A matching question on types of chloro-derivatives and their examples.

Find: The correct correspondence between LIST-I and LIST-II.

Identify each compound from the position of the chlorine atom.

  1. Vinyl chloride has chlorine directly attached to a carbon of a double bond:
CH2=CHCl\mathrm{CH_2 = CHCl}

So, A →\rightarrow III.

  1. Benzyl chloride has chlorine attached to the carbon next to the benzene ring. The aromatic structure shown in IV represents this case.

So, B →\rightarrow IV.

  1. Alkyl chloride has chlorine attached to a saturated carbon atom:
CH3−CH(Cl)CH3\mathrm{CH_3 - CH(Cl)CH_3}

So, C →\rightarrow II.

  1. Allyl chloride has chlorine attached to the carbon adjacent to a carbon-carbon double bond:
CH2=CH−CH2Cl\mathrm{CH_2 = CH - CH_2Cl}

So, D →\rightarrow I.

Therefore, the correct matching is A-III, B-IV, C-II, D-I. The correct option is B.

Classification by Position of Chlorine

Given: The names vinyl chloride, benzyl chloride, alkyl chloride, and allyl chloride.

Find: Which listed structure matches each name.

The classification depends on where chlorine is attached:

  • In a vinyl halide, chlorine is directly attached to a double-bonded carbon.
  • In an allyl halide, chlorine is attached to the carbon adjacent to a double bond.
  • In a benzyl halide, chlorine is attached to the carbon adjacent to a benzene ring.
  • In an alkyl halide, chlorine is attached to a saturated sp3sp^3 carbon.

Now compare with the examples:

CH2=CHCl⇒vinyl chloride\mathrm{CH_2 = CHCl} \Rightarrow \text{vinyl chloride} CH2=CH−CH2Cl⇒allyl chloride\mathrm{CH_2 = CH - CH_2Cl} \Rightarrow \text{allyl chloride} CH3−CH(Cl)CH3⇒alkyl chloride\mathrm{CH_3 - CH(Cl)CH_3} \Rightarrow \text{alkyl chloride}

The aromatic side-chain structure in IV is benzyl chloride.

Thus,

A−III,  B−IV,  C−II,  D−I\mathrm{A-III, \; B-IV, \; C-II, \; D-I}

Hence, the correct option is B.

Common mistakes

  • Confusing vinyl chloride with allyl chloride. This is wrong because in vinyl chloride, chlorine is directly attached to the double-bonded carbon, whereas in allyl chloride, chlorine is on the carbon adjacent to the double bond. Always check whether chlorine is on the double bond or next to it.

  • Confusing benzyl chloride with an aryl halide. This is wrong because in benzyl chloride, chlorine is not directly attached to the benzene ring; it is attached to the side-chain carbon next to the ring. Look for the benzylic carbon before classifying.

  • Treating every compound with chlorine on an sp3sp^3 carbon as the same category. This is wrong because benzyl and allyl halides are special classes identified by their relation to a benzene ring or double bond. First inspect the neighboring group, then decide the class.
